I want a reliable easy to setup nitrous setup to run a 50-70 shot. I'd prefer not to install any gauges. So this setup would have to be very safe. What do you guys recommend? Zex, NOS, NX? Do I have to run colder plugs with a 50 shot?

 

Zex is probably the fastest to put in and take out if you want the use and the flexability...I can recommend it highly. Over 50 shot colder plugs would be good depending on extent of usage.

but no I am not selling mine...


I do know of two members in So Cal here that have lightly used sets for sale...

Battle Max and Bernie2000SE ... hit em up for their costs...and good luck...

 

The ZEX kit is plug and play? I know the ZEX kit doesn't use a micro switch. Uses a voltage sensor?

I would not recommend running nitrous without a least a fuel pressure gauge, best to also have an EGT.

 

If you do not want to install any gauges, definately go with the NX Wet setup. It does not boost your fuel pressure like the dry kits and therefore the fuel pressure becomes a non issue.

You can easily run a 70 shot on the stock pump with a wet kit.

Also NO tuning is required with the wet kit because the fuel pressure is constant so you just put in the jets for your stock fuel pressure and its absolutely Jime (idiot) proof.

The main reason for tuning the dry kit is that you never know for sure what fuel pressure you are going to get with a given fuel jet it is almost always different in every car. So, you have to keep trying fuel jets until you get the fuel pressure recommended for a given shot.

I have been there done that, got the T-Shirt.

The only difference in the install is that you have to T into the fuel line.

PS I still don't recommend not having any gauges but if you want the safest non gauge way to go this is it.

One step colder plugs minimum, with a 70 shot I would recommend two colder for NX.

 

Why do people prefer the dry setup over the wet setup then? Are people just nervous about shooting fuel in to the upper part of the intake tract? Is it that they don't want to T in to the fuel lines? I don't think I'd go higher than 50 shot. Bah, I don't want to suffer huge performance loss when off the bottle from the colder plugs. Maybe nitrous isn't for me. =( It's kind of like an addiction. Install colder plugs, lose power off juice, makes you want to juice more. Run out of juice, cold plugs still in car, car looses hp, have to go pay money to the nitrous dealer!!!! OMG!! Nitrous is like drugs for your car!! Your car become physically dependent on nitrous. Haha..

 

People don't PREFER dry over wet they have just been fed a line of BS from NOS and its carried on. That mentality is pretty much over now people have caught on. I believe WET is SAFER than DRY.

One step colder plug is not even noticeable in performance N/A in my opinion, I run two colder all the time and don't notice any difference except it take a couple of minutes longer to warm up the engine.

Your choice, I am off the soapbox.

 

I read your review about the NX wet kit and you have me sold. Now I just have to think about it a little. I have to figure out a creative way to mount the gauges. I don't want them on the A-Pilar. Maybe in the pocket under the radio. I saw someone on this board have it mounted that way. =)

Hey Jim,

As you saw in the pix ... I finally got delivery of my NX kit!

What gauges are you running?

I was thinking these three:

1. Nitrous pressure (comes with the kit)
2. EGT
3. FP

Anything else?

 

Thats all I ran last year and I tried up to a 150 shot. Have you changed your fuel pump or are you planning to? You will be fine up to a 70 shot but after that you should upgrade. I never did get an electric FP gauge just ran the mechanical one with a hose stuck under the wiper blades, kinda inconvenient but I only spray at the track or on a deserted road to try stuff out.

You even got the bottle opener, which I don't have. I plan on putting mine in the back or front seat this year so I can open it from the drivers seat and I can see the bottle pressure without having a remote gauge.

I also bought a the S-AFC II so I can mess with the A/F ratio and read a bunch of other stuff as well. They are pricey though $300+.

 

Jime, I;ve been thinking about getting a wet set myself but, how safe is it to have the bottle in the cabin of the car with you?

 

Funny you should ask that. I plan on doing that this year. Not sure if I will put it on the floor in front of the front seat or on the floor in the rear. You do have to put a blowdown tube on though if its in the cabin. I already run the nitrous line through the cabin which is perfectly safe and legal.

I have a friend who has his in the front seat and he cut the bottom out of a sport bag and he puts it over the top to hide it. He has even been pulled over by the Police and they looked in his trunk but never saw the nitrous.

I am only doing it because its more convenient and I can open it with having a remote opener and keep an eye one it.

 

Kinda late, but just to add to this the dry setup does obviously work and many have used it. The reason NX wet setup works so well is that it atomatizes the fuel with the nitrous so well that u dont get any pools of fuel sitting around in the manifold which is what casues people to blow their manifolds off. The other kinda risky thing I would worry about the dry setup is it relys on ur fuel injectors to spray as much fuel in as possible to match the N20, but what if and injector fails while ur spraying? Just my .02

 

I have much the same questions. I do not care about gauges, I will do what ever is safest for my car, but I am looking for a reasonably priced set up that is user friendly. I am looking into a range of 55-75 shot because I do not want to have to get an upgraded fuel pump (plugs are no big deal), this car is just a stepping stone that I want to make a little faster for as cheap/(safe for the engine, it is still under warranty so please consider the ease of taking it off for warranty work) as possible (school bills)

Would it be Zex or NX, would I have to get out of my car each time I used it with one, or could I just open it up before I went to the track, and close it afterwards.

 

I think Zex would be the easiest to setup and remove, but the most efficient one would be NX, they have better warranties on their product then most any other n20 company. Nos would be a pain, especially if u go dry, dialing in the perfect A/F ratio can get anoying. With Nx or Zex its always the same, also u wont have to get in the trunk or nothing if u have a remote bottle opener.

 

Thanks for the reply. Why is NX more efficient, do they have an rpm switch or is it all manual?

 

The reason I say that, is becasue NX's HP rating is at the wheel. Were most rate the hp gains at the flywheel. So if u get a 75 shot, ur gonna get a 75 whp gain rather then 75 at the flywheel. Now I know for a fact NX rates em this way, but im not too sure about Zex. U can PM Jime to be 100% sure about the NX features, hes been runnin NX for a while now.

 

so what is the NX kit number for maxima 2002 if u r wanting to run around 50 to 75 shot.... or link to it to show the price...

also 10 pound bottle... how long do those last?

 

NX kit #20923.

It depends on the frequency of sprays the duration of each one.

Sorry .. my kit is still in my garage so I can't answer the 2nd question any better than that!

 

cool thanks for kit number
